Abstract

Telah dirancang suatu sistem kontrol kehadiran berbasis mikrokontroler AT89S51 untuk menginformasikan kehadiran dengan menggunakan kartu ber-paswword. Password dibuat dalam deretan 8 logika biner yang dipresentasikan oleh kombinasi bagian kartu yang berlubang dan tak-berlubang. Lubang-lubang digunakan untuk melewatkan cahaya dari 8 buah LED ke 8 buah fotodioda (jarak antara LED dan fotodioda adalah 0,5 cm) yang kemudian dibaca oleh mikrokontroler sebagai logika “1†(4,8 V ). Berdasarkan data 8-bit yang diterimanya, mikrokontroler kemudian memerintahkan relay untuk menyalakan ataumematikan lampu nama yang sesuai dengan password yang dimasukkan ke kotak detektor. Pada kartu terdapat dua password, yaitu password untuk masuk (hadir) dan password untuk keluar (pulang). Sistem detektor dijalankan berdasarkan program yang ditulis menggunakan bahasa pemrograman BASCOM. Hasil uji keseluruhan terhadap kinerja alat memperlihatkan bahwa alat dapat membedakan password untuk masuk atau keluar, dan membedakan pemilik password untuk masuk atau keluar, dan membedakan pemilik password yang satu dengan yang lain.
